RESUMO
BACKGROUND: The prevalence of mental disorders and substance use among prisoners is high. Convicted prisoners of 'good behaviour' can be part of a peer support system in prisons. AIM: To evaluate the feasibility of a peer support programme for prisoners with common mental disorders and substance use in prison. METHOD: The study used a mixed method research design, with a quasi-experimental approach (single group pre-post without control). It was conducted in two phases: Phase I. Thirty-five peers/convicted prisoners were recruited through advertisements on the prisoners' community radio station. Volunteers with good behaviour reports were given training over 5 days to recognise mental and substance use disorders and provide basic peer support in prison; their attitudes and knowledge were tested before and after the training. PHASE II: Feasibility of the peer support programme was tested by (i) recording the number of cases identified and referred, (ii) pre- and post-evaluation of well-being, coping, and symptom severity of those supported and (iii) evaluating qualitatively the experience of the peer supporters and service users. RESULTS: Thirty-five peer supporters identified 49 cases over 3 months. These cases showed significant improvement in well-being (Z -1.962; p < 0.050) and reduction in symptom severity (Z -1.913; 0.056). There was a significant improvement in the peers supporters' self-esteem from pre- to post-training (t -3.31; p < 0.002), improvement in their benevolence (t -4.37; p < 0.001) and a significant reduction in their negative attitudes to mental illness (Z -3.518; p < 0.001). A thematic model of peer support encompassed self-experienced benefits for the peer supporter, wider recognition of peer supporters in the prison, challenges to this kind of support, experience of training and visions for future work. CONCLUSION: The peer support programme was experienced positively by the peer-supporters and supported. Common mental disorders, substance use and suicidality were recognised and appropriately referred. A full-scale evaluation of this promising programme is warranted.
